Abstract

A method and terminal for sending a scan report based on a multi-carrier system are provided. The method comprises the following steps: a terminal acquiring a first configuration parameter of carrier(s) indicated by a base station and a second configuration parameter needed for the terminal to send a scan report, wherein the carrier(s) indicated by the base station is one of or a plurality of carriers of the base station and/or a neighboring base station of the base station; and the terminal scanning the carrier(s) indicated by the base station according to the first configuration parameter, generating a scan report, and sending the scan report to the base station according to the second configuration parameter.

Claims

1. A method for sending a scan report based on a multi-carrier system, comprising:

a terminal sending a scan request signaling to a base station;

the terminal acquiring a first configuration parameter of carrier(s) indicated by the base station and a second configuration parameter needed for the terminal to send a scan report from a scan response message which the base station sends to the terminal in response to the scan request signaling, wherein the carrier(s) indicated by the base station is one of or a plurality of carriers of the base station and/or a neighboring base station of the base station; and

the terminal scanning the carrier(s) indicated by the base station according to the first configuration parameter, generating a scan report, and sending the scan report to the base station according to the second configuration parameter.

2. The method according to claim 1, wherein the carrier(s) indicated by the base station is fully-configured carrier(s).

3. The method according to claim 1, before the terminal acquires the first configuration parameter and the second configuration parameter, the method further comprises:

the base station determining the carrier(s) indicated by the base station that the terminal needs to scan;

the base station setting the first configuration parameter of the carrier(s) indicated by the base station;

the base station setting the second configuration parameter needed for the terminal to send the scan report; and

the base station sending the first configuration parameter and the second configuration parameter to the terminal.

4. The method according to claim 1, wherein the first configuration parameter comprises at least one of the following:

identification(s) of the carrier(s) indicated by the base station, frequency(s) of the carrier(s) indicated by the base station, and bandwidth(s) of the carrier(s) indicated by the base station.

5. The method according to claim 1, wherein the second configuration parameter comprises at least one of the following:

an identification of whether to send the scan report, and a mode of sending the scan report.

6. The method according to claim 1, wherein the scan report comprises information of carrier(s) scanned by the terminal, wherein the information comprises at least one of the following:

the number of the scanned carrier(s), identification(s) of the scanned carrier(s), frequency(s) of the scanned carriers, and bandwidth(s) of the scanned carrier(s).

11. The method according to claim 2, wherein the first configuration parameter comprises at least one of the following:

identification(s) of the carrier(s) indicated by the base station, frequency(s) of the carrier(s) indicated by the base station, and bandwidth(s) of the carrier(s) indicated by the base station.

12. The method according to claim 3, wherein the first configuration parameter comprises at least one of the following:

identification(s) of the carrier(s) indicated by the base station, frequency(s) of the carrier(s) indicated by the base station, and bandwidth(s) of the carrier(s) indicated by the base station.

13. The method according to claim 2, wherein the second configuration parameter comprises at least one of the following:

an identification of whether to send the scan report, and a mode of sending the scan report.

14. The method according to claim 3, wherein the second configuration parameter comprises at least one of the following:

an identification of whether to send the scan report, and a mode of sending the scan report.

7. A terminal, comprising:

a sending module, configured to send a scan request signaling to a base station;

an acquiring module, configured to acquire a first configuration parameter of carrier(s) indicated by the base station and a second configuration parameter needed for the terminal to send a scan report from a scan response message which the base station sends to the terminal in response to the scan request signaling, wherein the carrier(s) indicated by the base station is one of or a plurality of the carriers of the base station and/or a neighboring base station of the base station; and

a scanning module, configured to scan the carrier(s) indicated by the base station according to the first configuration parameter and to generate a scan report;

wherein the sending module is further configured to send the scan report to the base station according to the second configuration parameter.

8. The terminal according to claim 7, wherein the first configuration parameter comprises at least one of the following:

identification(s) of the carrier(s) indicated by the base station, frequency(s) of the carrier(s) indicated by the base station, and bandwidth(s) of the carrier(s) indicated by the base station.

9. The terminal according to claim 7, wherein the second configuration parameter comprises at least one of the following:

an identification of whether to send the scan report, and a mode of sending the scan report.

10. The terminal according to claim 7, wherein the scan report comprises information of carrier(s) scanned by the terminal, wherein the information comprises at least one of the following:

the number of the scanned carrier(s), identification(s) of the scanned carrier(s), frequency(s) of the scanned carrier(s), and bandwidth(s) of the scanned carrier(s).
